Abstract: This paper provides a mathematical study to characterize the impact of isolating infected population in the dynamics of diarrhea epidemic. System of non-linear differential equation (consists five human compartments S, I, E, Ih, R human compartment) is used to determine a certain threshold value (known as the basic reproductive number R0 that represents the epidemic indicator obtained from the Eigen value of the next-generation matrix) to model the impact of isolating infected population in the dynamics of diarrhea epidemic. The equilibrium points of the model are calculated and the stability analysis of the numerical simulation has been shown. We investigate the local asymptotic stability of the deterministic epidemic model and similar properties in terms of the basic reproduction number. If at least one of the partial reproduction numbers is greater than unity then the disease will persist in the population. The disease free equilibrium point is locally and globally asymptotically stable when R0 < 1 and unstable when R0 > 1. Numerical simulation of the model is carried to assess or supplement the impact of isolation on the dynamics of diarrhea disease. Numerical simulation results show that as the rate of isolation is increases, then the recovered populations also increase. According to sensitivity analysis of the model, we presented numerical simulation results that confirm theoretical findings and the work has been illustrated through figures for different values of sensitive parameters.

Abstract: Hypertension (High Blood Pressure) is a major public health issue and an important research topic because of its great incidence and role as a key risk factor for cardiovascular disease and other consequences. The goal of this study is to determine the association between gender and blood pressure, as well as to determine which race suffers the most from high blood pressure among study participants. It may be concluded from the findings of this study that elderly persons have a larger risk of high blood pressure than younger people. High blood pressure is also more common in African Americans (AA) than in other races. Women are more likely than men to have high blood pressure, and smokers are more likely than nonsmokers to have high blood pressure. Physical activity aids in the burning of calories, which aids in weight loss. As a result, thick and hefty persons have a larger risk of high blood pressure than small people. Obesity and advancing age have been shown to be independent risk factors for high blood pressure. Improvements to surveillance systems are required, as is the introduction of community-based screening programs for the early detection of high blood pressure. Because there was a lack of understanding of high blood pressure among high blood pressure patients, improving health literacy to raise awareness of high blood pressure is also a pressing necessity. Weight control improved physical activity, increased fruit and vegetable consumption, and smoking ban are all essential and suggested interventions.
